Technical Field

The invention relates to the technical field of declination and magnetic moment detection equipment, in particular to a permanent magnet declination and magnetic moment detection device.

Background

The magnetic declination of the permanent magnet refers to the declination of the final magnetization vector direction of the permanent magnet. In the process of magnetic orientation forming of the permanent magnet, the orientation direction of a product is not parallel to the orientation magnetic field direction to generate a magnetic declination, or in the process of product interaction, the product is not aligned when being clamped, so that the magnetic declination is generated between the geometric symmetry axis of the product and the magnetic axis of the product. Due to the existence of the magnetic declination, a magnetic field is generated in the non-magnetization direction of the magnet, and a stray magnetic field is formed. With the continuous deepening of the application of the permanent magnet, the magnetic declination becomes an important influence factor on the performance of the precise magnetic device. Therefore, declination has become an important index for measuring the performance of permanent magnets, and the measurement of declination is more and more emphasized.

The three-axis Helmholtz coil and the three-channel fluxmeter are adopted to directly measure magnetic moments Mx, My and Mz in three directions, and vectors and vector synthesis in the three directions are directly displayed by matching with automatic control and calculation software of a single chip microcomputer. The deflection angle of the magnetizing direction can be directly selected, and whether the magnetizing deflection angle control range is met or not can be judged by comparing the deflection angle with a preset value angle.

The existing permanent magnet declination and magnetic moment detection devices are low in automation degree, low in labor efficiency, high in cost and high in error probability, so that the permanent magnet declination and magnetic moment detection devices are required to be optimized to reduce labor and equipment cost, improve efficiency and reduce error rate.

The blanking mechanism 5 is arranged at one side of the starting end of the conveying mechanism 2 in the running direction, and the blanking mechanism 5 and the feeding mechanism 1 are positioned at two sides of the conveying mechanism 2. The blanking suction needle of the blanking mechanism is made of magnetic conductive materials and reciprocates up and down along with the module mounting block, so that reliable stacking of blanking permanent magnet samples in the material clamp is guaranteed. The blanking mechanism sorts, blanks and stacks qualified products passing the magnetic flux detection, and unqualified products are placed in the isolation box.

The complete permanent magnet workpiece declination and magnetic moment detection method comprises the following steps:

1. the pushing cylinder 102 drives the pushing pin 103 to push the permanent magnet workpiece in the material clamp 104 to the tail end of the material channel along the material channel of the pushing plate 109;

2. the servo module 402 of the transplanting manipulator mechanism 4 moves to the suction position of the feeding mechanism 1, the positioning cylinder 406 and the suction cylinder 407 respectively drive the material removing head 409 and the material suction head 408 to descend to the proper position, and the resetting is carried out after the workpieces are adsorbed;

3. the servo module 402 of the transplanting manipulator mechanism 4 moves to the material falling position of the conveying mechanism 2, the positioning cylinder 406 and the material sucking cylinder 407 respectively drive the material removing head 409 and the material sucking head 408 to descend to the right position, and a workpiece is placed in the groove of the material receiving block 206 and reset;

4. the synchronous belt conveyor belt 202 drives the workpiece to the detection coil 302, and the workpiece starts to detect magnetic declination and magnetic moment data when leaving the coil;

5. the synchronous belt conveyor belt 202 drives the workpiece to return to the original position; performing adsorption action in the same step 2;

6. the transplanting manipulator mechanism 4 places qualified workpieces to be detected in a detachable permanent magnet material clamp 502 of the blanking mechanism 5, and places unqualified workpieces in an isolation box 6;

7. and (4) double-station bidirectional detection, and repeating the steps 1 to 6 in the other direction.
